MACHINE FOR PLACING FLIIPPEB STRIPS ON THESE BEADS.

Application filed January To all whom 'it may concern:

Be it known that I, lVAii'rnn (mnnocnr,

- a citizen of the United States of America.

residing at Conshohocken, in the county of Montgomery and State ofPennsylvania, have invented certain new and useful Improvements inMachines for Placing Flipper Strips on Tire Beads, of which thefollowing is a specification.

My invention relates to new and useful improvements iin machinesitorcovering a tire head. or as known in the art, placing the flipper strion the tire bead.

One of the o jects of the present machine is to so construct the samethat it will be possible to neatly apply the flipper strip to the headin an extremely rapid manner,

in fact, in from five to six seconds depending somewhat on the skill ofthe operator, and the rate at which the machine is'run. Still anotherobject of the invention is to provide amachine wherein the circular beadmay be quickly placed on a set of rolls by simply lifting apivotedcarriage. after which the flipper strip will he placed ,under the beadand against the first roller arid the machine then started. the beadquicklj making a complete revolution and the flipper strip being forcedtightly around the head, one portion left extending outwardly 'hoyondthe side of the head, o that this strip may be interposed as usualbetween the layers offahric when the carcass of the tire is assembled.

At times the beads are provided with an enclosed wire. and the headshave a tendency to retain their circular shape while being handled bythe operator. To allow for this form of head. the present inventioncon.- templatcs the raising of the central rollers, and the three pairsof these rollers will be about the arc of'a circle. thus doing away withthe necessity ol making-the head lie in a horizontal plane when passingthrough the machine.

Still another object of the invention contemplates the construction of amachine having a tillablc carriage carrying: a series of small rollersand also a meaiis for guidinn" the flipper strip inwardly and over thehead so that the last two series oi rollers will rightly press theflipper strip to the head. Also. in conjunction with this guiding "meansand tiltalile carriage, a guide block with a V-shaped groove is used,the rear 21, 1925. Serial N0.'3,157.

portion of the same being in a higher lane than the front portion, sothat the flipper strip will be pressed tightly against the three sidesof the bead and at the same time will allow for and guide the portion ofthe flipper strip that extends outwardly from the top of the bead.

Still another ohjec't of the invention is to provide a machine which issemi-portable, comprising a base or standard with a motor mountedthereon, which motor is to run the mechanism for placing the flipperstrip on the tire head. This mechanism comprises primarily three sets ofrollers, one in each' set being spring-pressed, while a springpressedadjustable guide plate operates in conjunction with a guide block andthe series of rollers aforementioned, sothat the flipper strip may heapplied neatly and accurately within a space of about live or sixseconds. i I

With these and other objects in View, the invention consists in certainnew and novel arrangements and combination of will be hereinafter morefully descri ed and pointed out in the claims.

Referring now to the drawings showing a preferred embodiment of thelnvention,

the tire bead titted,

.Referring now to the several views, and

ill

is secured the rod 4 which in turn operates the fork 5 for advancing orretarding the, one face of the clutch 6 mounted on the shaft 7 of themotor 8. The upper portion of. the pedestal 1 is rounded so that acollar 9 may be secured thereon, on which is fastened a shaft or bracket10, on which the motor 8 is mounted. A set screw 11 is shown forfastening this bracket in the desired position on the rounded portion ofthe pedestal 1.

Mounted at the upper end of the pedestal 1 is the gear box 12, asuitable collar 13 being provided in which is the set screw 14 so thatthis gear box may be adjusted in a rotatable manner 'to properly alignthe shaft 7 of the motor and the clutch face 6 with the component clutchface 15, the latter mounted on the short stub-shaft 16,-

which shaft is mounted in a bearing 17 secured to the under surface ofthe gear box 12. As far as the specification has proceeded, it will beseen that a pcdestal, motor and clutch have been provided with means forengaging and disengaging the clutch, while the motor and gear boxtogether with their mountings are so arranged that the motor may beadjusted in a vertical manner, and further that the gear box and motormay also be adjusted in a horizontal manner so that the motor may becorrectly aligned.

Mounted on the small shaft 16 is the worm 18 designed to mesh with thegear 19 mounted on the shaft 20, which, in turn, is suitably mounted asat 21, and extends into the gear box, and o erates or revolves thedriving gear 22. T is drive gear 22 is designed to mesh with the gear orpinion 23 which in turn is mounted on the small stub-shaft 24 thatextends outwardly through the opposite side of the gear box to drive theroller 25 as may be seen in the several views. This shaft passes throughthe small hub 26- against which the roller .25 bears.

There are two more of these rollers 27 and 28. and similarly there arethe respective shafts 29 and 30 and a small hub is also provided similarto the hub 26, oneach of these shafts. On the opposite ends of theseshafts 29 and 30, are the gears 31 and 32 and to complete the train,idlers 33 and 34 are provided so that a movement of the gear 22 willdrive these rollers inv the same irection.

Referring to Fig. 7 for the moment. these rollers are each provided witha groove 35 which is preferably V-shaped to accommodate the V-shaped ortr1angular head 36. as also shown in Fig. 8

Referring now to therollers 25, 27 and 23. it will be seen in Fig. 1,that they are arranged in a horizontal plane and 1nasmuch as some tireheads have a wire (not shown) molded within the bead, it is desirabletorun the head through the machine in a circular path as shown in Fig.5, rather than in a horizontal plane as shown in Fig. 1.

The machine may be. made with the rollers 25, 27- and 28 in thehorizontal plane,

.as in Fig. 1, or they might be fixed y set in the position as shown inFig. 5, but

,in the present application to accommodate either form of head, I haveshown an arrangement whereby the roller 27 may be" adjusted verticallyand set in an adjusted position.

In Fig. 6 the ear 31 is shown on the shaft 39, and it W1 1 be noted thatthe shaft is rotatably mounted in the small plate 37 which is rovidedwith a tongue 38 which is adapte to ride ina slot 39 formed in the faceof the gear box 12. A slot 40 is formed in the small plate 37 so thatthis plate, with its shaft and gear, may be locked by a bolt and nut 41shown in Fig. 3. By so mounting this shaft 29, which of course willcarry the roller 27, the roller and gear may be raised to have the axesof the three rollers in the arc of a circle, or it may be lowered to theaxes of the other rollers, thus accommodating a bead with or without awire molded therein.

,the rollers 28 and 27 there is positioned a guide block 42 which ismounted on a small bracket 43 formed on the shelf 44 on the face of thegear box, the frontportion 45 of the same adapted to extend to the planeor just above the plane of the upper surface of the rollers,'while. therear portion 46 is adapted to extend in a higher plane than the portion45, so that the flipper strip 47,

afterwards to be referred to, will be guided on the further side of thebead against the bead and up and over the portion 46 of the guide blockto assume a position as clearly shown in F ig. 8. This guide block 42 ispreferably rounded near its opposite ends as at 48 to allow for theperiphery of the rollers and at the safe time to extend partly over theperiphery of the rollers.

as may be seen in Figs. .1 and 5. I

To make it possible to adjust this guide block, I have provided a slot49 in the bracket 43, and also a. slot in the guide block 42 for thewing nut 50. When the bead 36 without a wire is to he used, the guideblock 42 will be in the position shown in Fig. 1 and will be changed tothe position ill terrace as shown in Fig. 5 when a head is used having aWire molded therein. A guideplate 52 is positioned directly above thisguide block and will he shortly described.

Referring; now to the pivoted carriage 53 it will be noted that abracket is mounted on the top of the gear box in the arms of tive slotso that springs may be placed against the outer surface of the hubs andbear against the small bracket arms 61 secured to theend of therespective rods 57. liloun'tod on each of these arms is the roller sothat when these rollers contact with the dipper strip on the bead theywill be spring-pressed to thereby tightly press the flipper strip inplace, out at the same time he allowed to vary slightly in theirpressure thus allowing, for different size beads or nregnlarities, etc.

A further hub 63 is shown on the carriage plate, in which is likewisemounted a rod 64 having the pin -65 pasing through the slot so "formedin the lower portion of the said hub 63. (in the lower cud of the rod()4 the little support or head (37.. which in turn carries the guideplate 52 heretofore referred to, and this guidc plate is slightlyadjustable with regard to the head 67 by providing the slots 68 in thehead and us ng; small wing nuts 69 in these slots and bearing; on theplate 52. A

This guide plate. as may be seen in Figs. 1,3 and 4 is designed toextend at an angle to the central roller to force a portion of thedipper strip downwardly on the top surface of the bead and to guide theflipper strip across the bead before being pressed. as

clearly shown in Fig. 4.

It is neces ary that tho flipper strip .bc initiuilly positioned whenpassing under the first roller and to'lbc second roller. and ior thispurpo e small bracltct 70 mounted in a slot 71 on flu-1 cm box-and hasthe little adjustable guide 72 along its one edge to correctlyncconuumlatc the width of tho flipper strip 4-? and to center theflipper strip with regard to the bend. it will be understood that when lsay confer the fiipper strip, i mean. correctly position the flipperstrip with rcanrd lo tbc bead, so that one edge of the flipper stripwill extend shortly beyond the edge of the bend, While the remaining;'portion of the flipper strip will encircle the bead and extend outwardlybeyond the first mentioned edge so that the layers of fabric in thecarcass may be aitcn wards attached hereto.

@ ust above this bracket 70 is the hook 73 over which the head 36 willbe hung, but if the head has a wire therein, the hookwill not be used.

An apron T4 is shown attached to the pedestal to hold the head .36 inangular relation to the machine, so that it will not interfere with theflipper strip as it is fed through the carriage into the machine. \Vhcnit desired to raise the carriage 53, it is only necessary to force thehandle 75. upwardly, which handle is mounted on the gear box 12 andconnected with the rod 76 to the carrings 53, While to partly balancethe weight of the carriage, a counterweight 77 is slidably mounted onthe rod 78, which in turn is secured on the pivoted carriage.

The operation of the device is exceedingly simple, and is as follows:-Supposing that it is desired to cover a head in which there 13 noembedded wire, the small handle 75 will be forced upwardly to raise thecarriage 53, and the circular head then placed over the rollers 25, 27and 28, so that the inverted triangular head will fit within the groovesof these three rollers. will then be lowered and the flipper stripglaced within the small bracket 70 which as previously had the arm 72adjusted, and the flipper strip then laced'under the bead and againstthe first r0 ler. The foot trcadle 3 will then be depressed, which inturn throws the clutch of the motor into opera tion and imports movementtothe three rollers through the train of gears previously The carriagementioned. The dipper strip is then guided by the angularly positionedguide plate 52 as well as by the grooves in the first roller and thegroove in the guide block, so that by the time the flip er strip passesbetween the two central rollers, it has completely encased the bead andit is firmly pressed into position, and is then again pressed tightly bythe third set of rollers.

Of course the flipper strips are cut to the I desired length beforebeing. inserted into the machine, and after the head has made a completerevolution, the foot pedal is releascd, so that the clutch is thrown outof operation. The handle 75 will again be operated to raise thecarriage, and the now completcly covered head will be removed frombetween the rollers, a new head thrown over the hook and the cyclecontinued.

This talzcs about live or six seconds, so that it is possible to make orcover eight or ten beads within the course of one minute.

The operation with a bead having" a wire molded therein is exactly thesame. but of course the center roller will be slightly raised andlOCltOd into position, and the guide block will be set so that it isnotnccessary to have the bead in a horizontal plane when passing throughthe three sets oi rollers.

By providing this guide block between the first two sets of rollers, andby proriding the angular late, and by having theguide block providiadwith a groove similar to the rollers, and the rear portion of the guideblock extending higher than the-front portion, the applying of theflipper strip to the head will he quickly and accurately done as theparts are so proportioned and arranged as to not only completely coverthe head, but to allow the stri to extend out from the head, as isdesireI :xn aware that it is old to provide a series f rollers for applying aflipper strip to the bead, and that it is old to use groovedshapedrollers, and I do not claim the invention broadly as such, but what I doclaim and desire to secure by Letters Patent is 2- 1.
